In short
Good for
- Subzero winter camps and cold belays, standing around
- Winter walking and climbing, over a shell
- Cold-weather use where a lot of down matters more than weight
Strengths
- 290 g of 700 fill power recycled down in big baffles
- Longer cut and helmet-compatible hood with a wired peak
- Two-way zip gives access to a harness
- Several pockets, including an internal chest pocket and two internal stash pockets
Weaknesses
- 645 g for size M, in the 600-799 g band
- Warmth, damp performance and durability aren't scored: no independent test of the current version found
- No packed size or volume published
- Alpkit states a 700 fill power but not the test method
- On pre-order: Alpkit says despatch from 2 November 2026; the 20D outer is thin and Alpkit says the DWR only shrugs off light rain and snow
